Mine have been guilty of doing the exact same thing! I remember when I got ready to redecorate the living room in my old house, Scott helped me get the wooden shutters out of the window and low and behold, Roger and Milly had chewed them up almost completely from the back side!! LOL!!!! They started the same thing here on a closet door with louvers (sp?), again from the inside. That's about the time that I moved them into a different room and Scott and Andrew built their "gym" to distract them!!!

Bad birdies!!!!!
